Defined in header `<cmath>`

float asin( float arg );

double asin( double arg );

long double asin( long double arg );

Computes arc sine of arg

arg - floating point value

arc sine of arg in radians in the range of [-π/2; π/2] radians.

Domain error occurs if arg is outside the range [-1.0; 1.0]. NAN is returned in that case.
